RB2 on the Wii is just like the 360 version.
I didn't mind the stripped-down version of RB1 on the Wii. I really don't care for making my own character and stuff like that.
I got Rock Band for the Wii, and it was worth the insane price. I love most of the songs it has, and the drums are really fun to play.
It gets even better when a friend comes over. Multiplayer is much more fun than playing by yourself.:cool:
